WIRE-GUTTNG MACHIE.

Application filed October 20, .1927. Serial No. 227,473.

My invention relates to the. class of machines employed tor cutting wire into certain lengths and an object oimy invention, among others, is to obtain a mechanism for receiving the severed lengths oi wire and for discharging said lengths7 said mechanism being of simple construction and eilicient in operation.

A portion of one form or' machine embodying my invention and in the construction and use of which the objects herein set out, as well as others, may be attained, is illustrated in the accompanying draw-ings, in which.

Figure 1 is a view in side elevation of one end of a wire straightening and cutting machine illustrating my improved mechanism connected therewith.

Figure Z is a perspective view showing this connection.

While my invention is notliniited to use' in connection with any special type of wire'cutting machine, yet asit linde ready adaptation in connection with a wire straightening and cuttingmaehine, l have illustrated such herein for the purpose of explaining my invention, in whichk drawings the numeral 5 indicates the base of a wire straightening and cutting machine, 6 a standard rising therefrom, 7 a'cam shai't having one end rotatably supported in said standard and having a cam 8 for operating a shifting lever 9 employed to operate a l sliding member 10 mounted 'for reciprocat- -ing movement in a bearing l1, the sliding member supporting a stationary cutting die and a cutter head 12 rotatably mounted on said member and having a movable cutting die to cooperate with said stationary cutting die. rllhe member 10 has a lengthwise opening l through which a wire 18 extends that may be delivered from a straightening mechanism in Va manner common to machines of this class. The cutter carrier or sliding member 10 is reciprocated by the lever 9 in order that the cutters may move with the Wire while a length is being severed by said cutters. All of the mechanism thus far described is of old and well known construction andiiurther illu-stration and description thereof are omitted herein.

The oscillating member of the cutters is 0perated as 'by means of a toothed segment 111 rigidly connect-ed with said member and having its teeth meshing with the teeth oi a segment 15 on the end of a cutter' actuating lever 16 secured to one'end oa rock shaft 17 mounted in bearings on the fra-me includ-ing the standard 6. The leverl6 is actuated'by a bar 18 pivotally attached at its upper end tosaid leverand having a roller 19 at its lower end engaged within a cam groove in a cam 2O secured. to and operated by the cam shaft 7.

The wire receiving mechanism comprises a trame including standards 21, one only ol which is shown herein, it being understood that there will be two or more of these structures to support the opposite ends ot' members shown herein as supported at one end by the standard 21. These standards may be connected as by means or' a supporting bar 22 secured to and extending from the standard 6. f y f A box 23 in the form of a bar with a groove in its under surfaceis secured to theu'nder side of brackets 24textending upwardly from the upper ends ofthe standards 21j and a wire rest'25 is movably mounted to close the open side ofthe groove inthe box, as shown herein this opening being in the under side of the bar constituting the box. This rest is secured to the upper sides otsupporting n arms 26 securedto and projecting froma releasing shaft 27 mounted for rocking 9 ythe two'menibers, as herein shown a block.'

pivoted on the arm 29 being located in a slot in the end of, the lever 28, and as shown in Figure 3 ofv the drawings. From this description, taken in connection CIT with the accompanying drawings, it will be noted that the mechanism `for releasing a severed length 30 ot wire is operated simultaneously with and by the mechanism for operating the cutters.

The wire rest is located in the position shown in Figure 2 while the wire is being projected through the cutters and before it is severed, the restin connection with the box therefore serving as a guide tor the wires. Upon the downward movement of the bar 18 to operate the cutters to sever a piece of wire the connect-ions between tine rock shaift 17 and the supporting arms QG, hereinbe'tore described, causes the latter to be withdrawn and remove the wire rest trom the trough in the box, and the severed length.

of wire is permitted to tali onto a support constituted by a curved edge ot the standards 2l and swinging 32 pivotaliv supported on the Standards 2l and operated by means of a rod 33 extending to a treadle operated mechanism (not herein shown but which is of old and well known construeN tion). A lip 3l on the end ot the wire rest 25 serves to guide the wire into the trougl in the box 23.

While the lever 28 and the arm t shown herein as integrally formed, it is obloosely mounted on the shaift, a: eliady shown in Figure 7. This *block has a loiy ing notch 35 in its end to receive a locking lug 36 progecting from one side oit a locking head 37. A retaining lug 38 projects 'from the o osite side or said head in nosition to engage a retaining notch 39 formed in the top of the standard 2l. The head 37 is pivotally mounted in a notch in the upper end of one of the supporting arms 26, which arm is extended a short distance above the shait, as shown in Figure 7 of the drawings. The head is adapted to have a rocking movement in the slot in the lever 26, as by means of an operating handle 40 that is removably atached to the head 37 'for this purpose. By this arrangement of parts the arm 26, in which the head 37 is mounted, is adapted to be locked either to the block 34 or to vthe standard 2l. `When not in use such handle may be placed in a socket /l-l in the standard.

The head 37 is vieldinglv retained in either ot its locking positions, as by means ot a spring pressed detent Ll2 in the arm 25 projecting to engage either one of two notches i3 in the under side of. the head', and

as shown in dotted lines in Figure el of the drawings.

,ln the use ot vthe device in this form when it is desired to operate the machine to retain the wires in the bon 23 until they are lcut ofil the lug 36 is engaged in the notch 35, as shown in Figure 7 in which position the machine will operate as hereinbctore described with recpect to the machine shown in Figures l to 3 through the medium of the arm 28 that rigidly connected with the block 3ft and is engaged with the actuating arm 29 in the same manner i hereinbet'ore described with respect to the device ot Figures l to 3.

it it be desired to uncover the opening in the bei; to retain the box thus uncovered 'for any reason, the head 37 is swung, as by means oi the handle Ll0, from the position shown in Figure 7 to a position to disengage the lug 3G from the notch 35. Said handle is then made use oi: to swing the arm 26 thus rotatin the shalt Q7 independently of the block 34; and to a position so that the lug 38 maj.' he engaged with the locking notch 39, in which position ot said arm the rest 25 will be removed to iuicover the opening in the bon, l the machine may be operated .if desired with the parts in this position.

in zccordance with 'the provisions oit the patent statutes l have described the principles ot operation ot my invention, together with the apparatus which l' now consider to represent the best embodiment thereof; but l desi rc to have it understood that the device shown is only illustrative, and that thel invention mayv be carried out by other means and applied to uses other than those above set out.
